Talk:Rhombo-hexagonal dodecahedron

From Wikipedia, the free encyclopedia

Removed statement just added: Unclear what the "symmeties" are, and not a very useful die with unequal face areas. Tom Ruen 01:47, 30 November 2006 (UTC)

It has 12 faces,over 120 symetries,and can be used as a 12 sided dice in board games.

I added that it has D4h symmetry, which looks like order 16 symmetries. Tom Ruen 02:17, 30 November 2006 (UTC)

[edit] Wigner-Seitz cell for a body-centered cubic lattice?

I a almost certain that a rhombic dodecahedron is the Wigner-Seitz cell for a *face centered* cubic lattice. Every lattice point in a FCC lattice has 12 nearest neighbors, so the Wigner-Seitz cell should have 12 faces. Every point in a BCC lattice has eight nearest neighbors and six second-nearest neighbors, and the Wigner-Seitz construction produces a truncated octahedron. Maybe the original author was thinking of Brillouin zones, which are Wigner-Seitz cells in reciprocal space. --Pciszek 04:08, 4 January 2007 (UTC)

I create the stub but I can't judge that addition. Tom Ruen 04:54, 4 January 2007 (UTC)
